Results page repeat ?

I have the search form with the following fields:
Awardtype (dropbox)
Lastname (textbox)
Firstname (textbox)
Event (dropbox)
Submit button for Search button. When I click on the search button, it takes me to the action page where display all the records from the database. It’s displayed 25 records per page and I have about 200 records from the database. It was displayed correctly on the first page which is 25 records, however, when I click next to move to the next page, I got no record, it should display another 25 records on the second page. I think because I lost all the search criteria on the second page? How do I do this in order to make it work for the rest of the pages? The code is attached, please tell me how.

Thanks
